I had an oil change done after approximately one year. I have not hit 10K miles yet. My wrench has been on now for about 3 months, I couldn't get it to turn off...

OH DEAR! You need to get that cleared out. It took me about a hundred tries, but I finally cleared mine.
Here's what I did:
CLOSED the door! (this apparently matters!!)
1: turn key on to position1
2: turn key off
3 turn key on to position 1
4: double click left button to bring up service interval (do not hold button in on last click)
5: turn key off
6: press and hold in firmly left button
7: turn key on to position 1 keep button held in firmly until resets
Again, it may take quite a few tries, so first of all be sure to write down the miles on your trip odometer if you are keeping a log!! You WILL reset it to zero a few times in the course of trying to reset the maintenance indicator!!
